Internet Explorer just shows a white box.

Below is the link:

I wrote in the article {avi}I inserted name of file here{/avi}

Plug-in is enabled and correct folder is identified in the plug-in.

My Joomla Version is 1.5.21

just put a you tube video on the same page using All Videos and it worked fine... just have to figure out why my avi file won't play.  :'(

My videos folder is located under images (I don't have a video folder under stories)... see attachments.  I'm not sure what else to do here.
